Typical swarm locations
Collectors regularly attend swarms in the older stone-built properties and churchyard trees around St Mary's and Wood Street, in the parkland and walled-garden remnants of the Bowood estate at Derry Hill, on the chalk grassland and scrub margins of Cherhill Down and Oldbury Castle, along the Marden riverside willows and watermeadow through the town, and in the chimney stacks and eaves of the older Victorian brick properties.
